I used the calculator, but it doens't input it like I would like it to.. (I tried using this (m^2-9)/(m^2-1) ∶ (m^2+4m+3)/(m^2-4m+3), but the result was far from what I needed)

This is how the equation should look like from the start: http://prntscr.com/enbg9t

Thanks in advance!

#1**+1 **

[ (m ^2 - 9) / (m^2 - 1) ] / [ (m^2 + 4m + 3 ) / (m^2 - 4m + 3) ] =

Invert the second fraction and multiply

[ (m ^2 - 9) / (m^2 - 1) ] * [ (m^2 - 4m + 3 ) / (m^2 + 4m + 3) ]

Factor where possible

[ (m + 3) (m - 3)] * [ (m -3) (m -1) ] / [ (m + 1) ( m - 1) * (m + 1) ( m + 3) ]

Cancel terms where possible

[ ( m - 3) (m - 3) ] / [ (m + 1) (m + 1) ] =

(m -3)^2 / (m + 1)^2 = [ m^2 - 6m + 9 ] / [ m ^2 + 2m + 1 ]
